CHATGPT PET FAQ
Web, desktop, and Codex are different.
Does a ChatGPT pet ZIP install on the web?
No. ChatGPT web uses the raw transparent sprite sheet. Pet Studio exposes that file separately from the Codex ZIP.
Do desktop pets sync to ChatGPT web?
No. Custom pets created in the desktop app are stored locally and do not automatically sync to the web experience.
